Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a nasal breathing mask. Background Art

[0002] A nasal respiratory mask is a medical device used in a ventilator that covers the user's nose and helps keep the airway open to ensure they can breathe normally. It is commonly used to treat diseases such as sleep apnea that require continuous positive airway pressure.

[0003] In existing respiratory nasal masks, the air inlet tube can only rotate on the horizontal plane, which limits the user's freedom to adjust the tube angle. At the same time, the headband has a limited adjustment range and poor stability. It cannot meet the needs of different users' facial shapes, nor can it adapt to different postures or activities, affecting the user's wearing comfort and the smoothness of the airflow.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] according to Figures 1 to 3 As shown, a respiratory nasal mask of the present invention includes an upper headband 15, a lower headband 16, a nasal mask body 1, an air intake nasal plug 2, and an air intake pipe 3. The air intake nasal plug 2 is connected to the outside of the nasal mask body 1. The air intake nasal plug 2 is provided inside the air intake nasal plug 2. Through this channel, air flows into the air intake chamber 6 inside the nasal mask body 1. The nasal mask body 1 is provided with a valve seat 4. The air intake pipe 3 is connected to the air intake chamber 6 through the valve seat 4, forming a complete airflow channel. The valve seat 4 is composed of an integrally formed inner ring 8 and an outer ring 9. The diameter of the outer ring 9 is smaller than that of the inner ring 8. The inner ring 8 is provided with a sealing portion 10 with a circular arc cross section. The sealing portion 10 contacts the valve ball 7 on the air intake pipe 3 to ensure the sealing of the airflow channel. The valve ball 7 is mounted on the air intake pipe 3 and is connected to the nasal mask body 1 by rotation. This allows the air intake pipe 3 to adjust its angle within a certain range, enhancing the adaptability and sealing effect of the nasal mask. A nasal mask support 11 is also provided on the nasal mask body 1, and a first headband slot 12, a second headband slot 13 and a third headband slot 14 are provided at the end of the support. The lower headband 16 is connected to the first headband slot 12, and the upper headband 15 can be optionally connected to the second or third headband slot 14 to adapt to different facial shapes and wearing habits, ensuring that the nasal mask is stable and not easy to slip during use.

[0026] The inner ring 8 is provided with a limiting portion 17, which is a 45° inclined surface. The function of this inclined surface limiting portion 17 is to limit the movement of the valve ball 7 to prevent the intake pipe 3 from excessively moving and causing component fatigue or even falling off.

[0027] The first headband slot 12 is horizontally positioned. The lower headband 16 is equipped with a first fitting portion 18 at its end. This fitting portion, constructed of Velcro, can be threaded through the horizontal first headband slot 12 and attached to the lower headband 16. It also fits over the chin, providing secure support and a comfortable fit. The lower headband 16 is equipped with a chin pad 22, designed to enhance wearing comfort by providing additional support and cushioning, reducing pressure on the chin. The second and third headband slots 13, 14 are tilted at a 30° angle relative to the horizontal, providing versatile wearing options. The upper headband 15 is equipped with a second fitting portion 19, also constructed of Velcro, at its end. This second fitting portion 19 can be threaded through either the tilted second or third headband slots 13, 14, and attached to the upper headband 15, ensuring the upper headband 15 is securely fixed to the back of the head and enhancing the stability and comfort of the nasal mask.

[0028] The mask body 1 is provided with a buckle 20, and the mask support 11 is provided with a slot 21. The buckle 20 is detachably connected in the slot 21, thereby improving the overall stability and facilitating assembly and disassembly.

[0029] The nasal mask support 11 is made of elastic silicone material, which has excellent softness and elasticity, can fit the facial contour comfortably, and provides good sealing.

[0030] The air inlet pipe 3 is provided with a plurality of exhaust holes 23 for exhausting excess gas, ensuring smooth air flow and reducing gas accumulation.

[0031] When using the present invention, the first fitting portion 18 of the lower headband 16 is passed through the horizontally arranged first headband slot 12 and fitted onto the lower headband 16 while being placed on the chin. Then, the second fitting portion 19 of the upper headband 15 is passed through the obliquely arranged second headband slot 13 or one of the third headband slots 14 and fitted onto the upper headband 15, while being placed on the rear end of the head. The appropriate headband slot is selected to ensure wearing comfort and stability. When wearing the nasal mask, the nasal mask body 1 is gently placed on the nose and face, and the air inlet channel 5 is inserted into the nostrils, ensuring that the elastic silicone material of the nasal mask body 1 and the nasal mask support 11 fits the facial contours tightly. The air inlet pipe 3 is rotated to adjust it to a comfortable position, ensuring that it does not affect normal breathing. Finally, the air inlet pipe 3 is connected to the ventilator, and the air flow enters the air inlet chamber 6 through the air inlet pipe 3, then enters the air inlet pipe 3 through the valve ball 7 and is inhaled into the nostrils.

[0032] The beneficial effects brought by the utility model are:

[0033] The utility model is provided with a lower headband and a chin pad, so that the mask can be worn on the chin, providing additional support and ensuring that the nasal mask does not slide or fall off.

[0034] Through multiple headband slots, users can adjust the connection position of the headband as needed to adapt to different facial shapes and wearing habits.

[0035] The utility model allows the user to freely adjust the angle of the air intake pipe to adapt to different postures and usage environments, thereby improving wearing comfort.

[0036] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
